Do you create your own section elevations strictly in AutoCAD? We'll show you how to use SketchUp to generate elevations during this process while also using Land F/X to confirm the final outcome of your design. We'll start in AutoCAD using the Land F/X SketchUp Connection tool and work our way through modeling the terrain while showing some interesting SketchUp plugins. Finally, we'll bring our section elevations back into AutoCAD and put everything back together for a final product.

0:00 – 5:43: Intro/TOC

5:43 – 10:09: Terminology: Which One is Correct?

Cross Section or Section (5:55)

Refers to a view that is cut

 

 

Elevation (6:20)

Refers to the outside of an object, with no cuts. Elevation view is typically a plain, flat view.

 



Section Elevation (6:50)

Merging a section and elevation view. It includes an elevation view as well as cuts to show context.


Sending layers and blocks into SketchUp using the Land F/X SketchUp Connection tool (10:10)

10:30 – 16:30: Different Workflows for Going from Plan View to Section View

Using LAYFRZ and Work Areas to Export Just a Selected Portion of a Design to SketchUp (10:30)

Sending only selected items (for example: just trees and no shrubs) into SketchUp using the LAYFRZ (Layer Freeze) command (10:30)

 

 

 

Using Work Areas With Layer Suffixes (11:30)

Isolating a specific area of the drawing to send to SketchUp using Work Areas with layer suffixes (11:30)

 

 

Using Match Properties to apply a layer suffix to several blocks (such as trees or shrubs) (13:00)

 

 

Exporting Lines and Topo as 2D vs. Section (from SketchUp) (14:10)

Importing the trees into SketchUp and deleting a face in SketchUp to allow the trees to import into the proper terrain and elevations (14:20)

 

Importing additional Work Areas into SketchUp (15:00)

16:30 – 33:17 Useful Tools & Plugins

Land F/X SketchUp Connection

Using the Land F/X SketchUp Connection to send layers to SketchUp (17:00)

 

 

SketchUp Sandbox Tool

Using the SketchUp Sandbox tool to create a terrain mesh (18:00)

 

 

Instant Road Nui (Vali Architects)

Using the Instant Road tool to create roads automatically on specific terrain (18:30)

 


Color by Slope & Color by Z (Chris Fullmer)

Determining the steepness (not grade percentage) of a slope using Color by Slope (19:29)

 

Showing a slope by entering the highest and lowest points using Color by Z (22:20)

 

Toposhaper (Fedo6)

Editing and adjusting contours using Toposhaper (23:40)

 

 

Question: The path in the topo model earlier in this webinar seemed to have been up above the terrain. How did you get it to lay back down? (27:30)

Answer: The Instant Road Nui tool

 

 

Demo of the Instant Road tool (29:00)

33:18 – end: Section Cut Tools

Using the Unconnected Lines/curves to walls tool to create a section plane to use as a temporary guide for section cuts (33:18)

 

 

Creating a section cut using the SketchUp Section Cut tool (34:05)

 

 

Right-clicking on a section cut to see menu options such as Align View and Create Group from Slice (34:55)

 

 

Super Section (Daiku)

Using Super Section to create a scene – a profile of a section elevation – and display everything in parallel projection (flat, straight-on look), and create a separate layer for the scene (35:40)

 

Creating a section slice and exporting it as a DWG (36:42)

 

 

Section Cut Face

Using Section Cut Face to create a section slice (37:55)

 

Exporting the section slice to a DWG (40:43)

 

Dropping in Spot Elevations and Slope Callouts (Land F/X tools) to show the elevations and slope of the section slice (42:15)

 

Exporting a view in SketchUp as a 2D graphic (either as a JPG, PDF, or DWG linework) (43:20)

 

Attaching an image of a SketchUp view to a DWG drawing as an Xref (44:30)

46:50 – end:

Creating a new User Coordinate System (UCS) to set up a view based on the view of the section cut (47:20)

 

 

Assigning the UCS to a particular Work Area (48:45)

 

 

Using our Restore UCS tool to move between views (49:15)

 

 

Selecting plants from within one of our Work Areas and aligning their positions  (50:50)

 

 

Dropping blocks into the section views (52:40)

 

 

Using our Site Color to add color to a section view (55:00)

 

Question: Did it take very long to prep the drawing and model for this webinar? (55:30)

Answer: It took a while to get the techniques down, but once we did, we were able to do the prep relatively quickly, if not in real time. It was a lot of work because of the copies that were necessary to show the different steps.

 

 

Creating a Section Cut in Real Time (56:05)

 

 

Cleaning up linework by stitching it together using our SuperJoin tool (58:30)
